next/script — strategy="lazyOnload"

Worst-case for v1 — lazyOnload waits for browser idle AFTER window.load to fetch the script. v1 listener can never observe window.load. Closest analogue to NitroPack on gorayeb.com. v2 should fire regardless since it does not depend on window.load.

Each side runs the same scenario in its own iframe. The iframes load independently, so you can see how each pixel version behaves under identical conditions.
